i am sorry , i need the second pic with the question 3

i post the wrong pic sorry

1. TNN Water Resource management company operates three reservoirs 1, 2, 3 with daily supply of 15, 20, and 25 kilo tons of fresh water, respectively. On each day, they must supply four cities A, B, C, and D whose demand are 8, 10, 12, and 15 respectively. The cost of pumping water from reservoir to city per kilo ton is given below (unit of 10 dollars): 2 3 4 5 C= 3 2 5 2 1 4 1 2 3 Formulate this problem as a Transportation problem, and use Vogel's method and transportation simplex to solve this problem, to determine the lowest cost pumping schedule. Assume that excess water can be disposed of at no cost. 2. Consider the problem of scheduling the weekly production of a certain item for the next four weeks. The production cost of the item is $10 for the first two weeks, and $15 for the last two weeks. The weekly demands are 300, 700, 900, and 800, which must be met. The plant can produce a maximum of 700 units each week. In addition, the company can employ overtime during the second and third week. This increases the weekly production by an additional 200 units, but the production cost increases by $5 per item. Excessive production can be stored at a unit cost of $3 per week. How should the production be scheduled, so as to minimize the total cost? (Use the Russell's method for the starting solution 3. A group of four boys and four girls are planning on a one-day picnic. The extent of mutual happiness between boy i and girl j when they are together is given by the following matrix (data obtained from previous dating experiences): 11 1 5 8 C9 9 8 1 10 3 5 10 1 13 12 11 3. Cor CS The problem is to decide the proper matching between the boys and girls during the picnic that will maximize the sum of all the mutual happiness of all the couples. Formulate this problem and solve as an assignment problem. (Note: this is a maximization problem)
